the COSINE Collaboration today presents the first results that significantly challenge DAMA’s claim of a dark matter observation. The paper, published this week in Nature, does not reveal any excess of interactions that could be attributed to dark matter.
Magnetic monopoles were predicted by Paul Dirac in 1931. Their existence would imply the quantization of magnetic and electric charges and, thus, symmetrize Maxwell’s equations with respect to the sources of the electromagnetic field. Today, these equations allow magnetic charges to exist only in pairs (north and south) while positive and negative electric charges can exist independently.
